Re: Airbus A320 Engine Fix Won't Come for Months, Lufthansa Says

History repeating itself. Just to be expected when pushing the state of the art. The problem is - these issues with the GTF are nothing to do with the gearbox. The compressor, combustor and turbine are definitely not leading edge (when compared to the Leap) The gear is not just done for fun! A 3x h...

Re: Why Anhedral with fly by wire?

The normal reason to have anhedral angle is for better stability Are you sure? Acc. Wiki dihedral would be much more stable. So anhedral on high mounted aircraft is done for increasing maneuverability. https://en.wikipedia.org/wiki/Dihedral_(aeronautics)#Anhedral Military fighter aircraft often hav...

Re: Why engine design partnerships?

Pratt invested how long in figuring out the cooling of the gearbox lightsaber, why is gearbox cooling such an issue? I've also seen quotes from RR engineers say that's a difficult issue. There's a big fan pumping huge amounts of air around the engine, and warming it up a little with a gearbox coole...

Re: Boeing expects $70M profit per a 787 frame in the future orders

So will Boeing will be able to keep the price level or will it below the planned cost. So in the end they account for example -30 mill. loss per frame but get 40 mill. cash or 40 mill. non-GAAP profit. This will be fun for the sales team especially with the pressure to fill the line.

Re: 'A buffet is not a takeaway': London hotel shames Air India's crew

It sounds like the crew eats at the buffet and then takes away another large amount of food to be eaten later. I am not aware of any hotel that likes this behaviour. It is allowed in the hotel I will stay in my skiing holidays. It is called lunch packet and they even provide material to take away:-...

Re: Airbus A320NEO Production Thread - Part 7

If you take the 23 number serious, it was not said engine shortfall in the tweet, but coordination issues.
You can of course not deliver engines if there are no frames for it.
I do not see the 11 frames that were near ready for delivery in 2016.

@Wacker1000
You are absolutely right. I had some issues with "whichever occurs later". The whole wording was quite logical for me in the way "whichever occurs ealier".

Re: Airbus A320NEO Production Thread - Part 7

I will not post the P&W data as comparision because it would make you very sad. Ignoring the QR aircraft, most of the old P&W inventory was delivered in Q4 2016. PW is still in the low 73xx, this is 100 MSNs lower e.g. 2 months delay to CFM and 3 months to standard. Of course we can ignore ...

Re: Airbus A320NEO Production Thread - Part 7

I guess the "one month delay" says it all. There is no real issue. CFM is nearly catched up. Nearly all CFM with MSN below 7400 are delivered. Only the test frames and MSN 7181 (seems to have a special issue) is left. The 1st Air Indias are MSN 7459+7475. MSNs you would expect to be delive...

Re: FAA Issues an AD for the 767-The most expensive ever?

Sorry, but you were all quite confusing and even wrong, if and when the AD has to be done. Every frame above 37500 cycles has to be done in the next 3 years. Every frame above 60000 cycles immediately. "Before the accumulation of 60,000 total flight cycles, or within 36 months after the effecti...

The main question is what is the conclusion. AB had 3 issue to tackle. SriLankan NTUs, Qatar deferring of any new frame as long as possible and the not fully solved seat issues for CX. 8 frame (MSN 47, 51, 55, 60, 63, 69, 70, 72) were not getting ready for issues not really controllable by AB.

plane:employees ratio I do not understand what this figure should be good for. I would understand an employee per seat or per million seat mile, but per plane? Who else should be high for this value than a VLA only carrier, but what else does it show that it is VLA only carrier. Strange, very stran...
